DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 A strong upper level ridge of high pressure lies on an axis from southern Nevada to northern Idaho. Offshore a deep upper level trough lies about 600 miles west-southwest of San Francisco and an upper trough is just off the British Columbia coast. At the surface the highest pressures are over western Montana and northern Colorado, while a reflection of the upper level low off the California coastline is located west-southwest of San Francisco. The net result of this will be a generally southeasterly transport. Smoke dispersal conditions will be good during the afternoons but collapse due to a nighttime inversion during the evening. 2.

OUTLOOK (THURSDAY - SATURDAY): Upper level trough in the eastern Pacific will gradually move in and bring a cold front to the region on Thursday. Upper level trough moves through Friday bringing scattered showers and continued cool, unstable conditions. A minor ridge moves in on Saturday bringing mostly dry weather but remaining cool and unstable. Smoke dispersion will remain good to excellent through the period. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Minor upper level ridge will shift to the east tonight making way for a weak front to move through the region tomorrow. Expect little to no moisture as the Cascades will wring out most of it. Air mass will destabilize as cooler air moves in aloft. Mixing will be poor during the morning hours but become good as the dry front moves in. Expect mostly poor to fair smoke dispersion. OUTLOOK (SATURDAY - MONDAY): Following Friday's front and minor trough, the upper level ridge will build in strongly over the weekend. Expect considerable warming through the period. Air mass will remain stable during the night and early morning hours but daytime heating should provide decent mixing during the afternoon on Saturday. Mixing worsens some Sunday and Monday. Wind flow will be mostly light offshore to light and variable, making for poor smoke dispersion. 2. DISPERSION FRIDAY Mixing height below 1000 ft early rising to 2300 - 3300 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 An upper level trough extending southwestward from a low in northern Alberta begins to move into the northwest Washington during the day on Wednesday. Temperatures aloft will be cooling dramatically, destabilizing the atmosphere and providing good smoke dispersal conditions. There will be limited moisture with this trough but some isolated showers are possible. Expect transport winds to be generally west to northwest most areas. OUTLOOK (THURSDAY - SATURDAY): The upper level trough sweeps through the region on Thursday further destabilizing the atmosphere over the Pacific Northwest. Again, limited moisture, but showers are possible especially over mountainous areas. The trough remains over the region on Friday for a continued chance of scattered showers but also good smoke dispersal conditions with high mixing heights. Saturday will see the upper trough well to the east, over the northern Rockies with surface high pressure centered several hundred miles west of Oregon. A minor upper disturbance dropping south-southeast will cause some instability for a continued slight chance of a shower but also continued good smoke dispersal conditions.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Upper trough transiting the area may bring a few showers this afternoon and tonight. Then clouds decrease. Friday will be mostly sunny and cool. Although a ridge is building over the eastern Pacific, it will remain far enough west to allow mixing heights to rise to 5000 ft or more during the day. Transport flow northwest to north through the day. All in all, Friday should be a good smoke dispersal day. OUTLOOK (SATURDAY - MONDAY): Ridge remains stationary to the west with cool northerly flow over the area. A couple of minor disturbances drop south from Canada with some cloudy periods over the weekend. Only the slightest chance of showers early Sunday. Mixing remains good as the ridge stays too far to the west to stabilize the air mass. Nighttime cooling will give poor mixing during the night and early morning. Low-level wind flow mostly northerly through the period. 2. DISPERSION FRIDAY Mixing height above 5000 ft through the afternoon. Mixing height lowers to 1800 - 2800 ft in the evening.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Models show an upper short wave moving down from the north on Monday to keep the atmosphere a bit unstable. Moisture is limited but there is a good chance for some mainly afternoon showers. Mixing heights should be quite high for good to excellent smoke dispersal conditions. Transport winds will be generally southwesterly. OUTLOOK (TUESDAY - THURSDAY): A second upper level short wave drops south on Tuesday eventually carving out an upper level low pressure area centered over Northwest Oregon.

Transport winds will be generally north-northwest. The upper low meanders ultimately splitting with a portion moving east and a portion retrograding to the west. Showers will end later Wednesday as the air mass stabilizes somewhat, but smoke dispersal conditions should remain good. Transport winds will remain generally north-northwest.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 The upper low that brought clouds, rain and cool temperatures to the Pacific Northwest will track west to east across the state on Wednesday. This will keep showers going thought the area. The cool air aloft with this system will keep mixing heights high and smoke dispersal conditions should be good to excellent. Transport winds will generally be northwesterly through westerly. OUTLOOK (THURSDAY - SATURDAY): On Thursday the upper low slowly pulls out to the east allowing weak ridging to build. Mixing heights should remain high for good to excellent smoke dispersal conditions. Expect a generally northerly or northwesterly flow across the region. On Friday a Pacific system approaches Oregon from the southwest. Computer models differ on the initial intensity of this system as it moves in. Right now it looks like precipitation will spread across the southern Cascades during the day and work its way northeast. Precipitation continues Saturday with warm over-running ahead of a Pacific cold front that moves into western Oregon. Smoke dispersal conditions should be favorable throughout the outlook period, but winds will be light and variable and conditions likely wet. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Upper level trough is exiting eastward and giving way to a temporary ridge for tonight and Friday. However, the next upper low and front will move up from the southwest later Friday bringing an increased chance of moisture Friday night. Air mass will stabilize during the morning under the ridge but afternoon heating will provide good mixing. Wind flow will turn offshore and provide decent smoke dispersion. OUTLOOK (SATURDAY - MONDAY): Upper level low moves in Saturday and weakens but will still produce some scattered showers over the region. Showers decrease on Sunday, and then another trough and front move in later Monday. This promises to be a stronger system, bringing fairly breezy conditions as well. Air mass will be mostly unstable during the afternoon and somewhat stable during the morning. Expect decent smoke dispersion. 2.
